a multicast source address, this argument has an effective value range of 0 to 32. 
The system default is 32 in both cases.

Use the reset igmp group command to clear IGMP forwarding entries.

Note that:

■

When clearing the IGMP forwarding entries of a VLAN interface, this command 
also clears the IGMP Snooping forwarding entries for that VLAN.

This command cannot clear IGMP forwarding entries of static joins.

robust-value: IGMP querier robustness variable, with an effective range of 2 to 5. 
The IGMP robustness variable determines the number of general queries the IGMP 
querier sends on startup and the number of IGMP group-specific queries the IGMP 
querier sends upon receiving an IGMP leave message.

Use the robust-count command to configure the IGMP querier robustness 
variable globally.

Use the undo robust-count command to restore the system default.

By default, the IGMP querier robustness variable is 2.
